A utility library for WPF projects

EasyWPF

EasyWPF is a utility library for WPF projects. It provides helpful attached properties to avoid having to create a whole Converter for simple and/or specific stuff.

Properties available for now:

• VisibleIf (works with a Binding or a direct value).
• VisibleIfOption (used by VisibleIf):
  • AlwaysVisible: Makes sure the element is always visible no matter the value.
  • HasItems: The element is only visible when the bound collection has at least 1 item (needs VisibleIf to be bound to an ObservableCollection, it also handles the CollectionChanged event).
  • IsNull: The element is only visible when the value is null.
  • IsNotNull: The element is only visible when the value is not null.
  • IsGreaterThanZero: The element is only visible when the value is greater than zero (using int.TryParse).
  • IsLessThanZero: The element is only visible when the value is less than zero (using int.TryParse).
  • IsEqualToZero: The element is only visible when the value is equal to zero (using int.TryParse).
  • IsDifferentThanZero: The element is only visible when the value is different than zero (using int.TryParse).
• VisibleIfCollapse (used by VisibleIf): If set to true, the element is collapsed instead of hidden.

Example:

<Button Content="Create Instance" easywpf:VisibilityHelper.VisibleIf="{Binding Instance}" easywpf:VisibilityHelper.VisibleIfOption="IsNull" />  

This Button will be visible as long as the property Instance is null.
